Preheat your oven to 375°F (190°C). Line a baking dish with parchment paper.
In a mixing bowl, combine the ricotta cheese, chopped basil, lemon zest, lemon juice, garlic powder, salt, and black pepper. Mix until well combined.
Place the salmon fillets skin-side down on a cutting board. Carefully slice each fillet horizontally to create a pocket for the filling, being careful not to cut all the way through.
Spoon the ricotta mixture into each salmon pocket, dividing it evenly between the two fillets. Press gently to secure the filling.
Place the stuffed salmon in the prepared baking dish. Drizzle with olive oil and sprinkle with grated Parmesan cheese.
Scatter the halved cherry tomatoes around the salmon in the baking dish.
Bake in the preheated oven for 20-25 minutes, or until the salmon is cooked through and flakes easily with a fork.
If desired, drizzle with balsamic glaze before serving.
